Web server not running on Zabbix server

[Neo]

I added Zabbix to the list if monitored hosts itself. (Is this ok?) Anyway on the Network map that I created it shows that the "Web server is not running".
Thats funny because I am using the webserver on the Zabbix server to view the pages that it is showing.
I had installed a new apache version and stopped the httpd (default) server. Does this have anything to do with it? If so how can I get zabbix to show the right status.
Or rather how do I replace the default httpd server with my Apache installed server? (yeah this would be better I think)

I have managed to replace the original httpd with the new version of Apache 2.0.54 but still the map says webserver is down
